Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention, in general relates to luggage and, more particularly, to a collapsible article of luggage.

Luggage comes in a variety of well known styles and sizes. Some types of luggage include zippers than are opened to allow a section to expand in order to create more storage space.

When people travel, they rely on luggage. Some types of luggage are used for short day trips, like attache cases or small carry-on types of luggage. Others are large and intended for the transport of more objects.

When they are home, their luggage takes up considerable space. It is desirable to be able to store their luggage in a compact space.

Also, sometimes when people vacation, they purchase souvenirs and other objects to bring back on their return. They often need more carrying capacity on a return trip than on the outgoing trip. Consequently, it is not uncommon to take an empty suitcase with them, yet this takes up valuable travel space.

Sometimes, people bring a collapsible duffel bag inside their primary luggage, but duffel bags do not provide any rigidity or protection to articles that are placed inside.

Accordingly, there exists today a need for collapsible luggage.

Clearly, such an apparatus would be a useful and desirable device.

2. Description of Prior Art

Luggage is, in general, well known. While the structural arrangements of the known types of devices, at first appearance, may have certain similarities with the present invention, they differ in material respects. These differences, which will be described in more detail hereinafter, are essential for the effective use of the invention and which admit of the advantages that are not available with the prior devices.

OBJECTS AND SUMMARY OF THE INVENTION

It is an object of the present invention to provide a collapsible luggage that is useful in carrying cargo items.

It is also an important object of the invention to provide a collapsible luggage that includes a first open position that is useful for carrying cargo and a second collapsed position for storage of the luggage.

Another object of the invention is to provide a collapsible luggage that collapses into a compact volume when not in use.

Still another object of the invention is to provide a collapsible luggage that includes at least a rigid portion attached to each side.

Still yet another object of the invention is to provide a collapsible luggage that includes sides that are hingedly attached with respect to a planar bottom member.

Yet another important object of the invention is to provide a collapsible luggage that includes a top member that is adapted to cover an opening into the luggage.

Still yet another important object of the invention is to provide a collapsible luggage that includes flexible corners.

Briefly, a collapsible luggage that is constructed in accordance with the principles of the present invention has a planar bottom, four upright sides that are hingedly attached to the planar bottom and a top member that preferably is detachable. The four upright sides includes flexible corners that permit them to fold down on top of the planar bottom. The top is then secured over the collapsed upright sides for storage of the luggage. To use the luggage, the upright sides are raised, the cargo is placed on top of the planar bottom intermediate the upright sides, and the top is secured in position over the cargo and the top edges of the upright sides.

DETAILED DESCRIPTION OF THE INVENTION

Referring to all of the drawings and now in particular to FIG. 1 is shown, a collapsible luggage, identified in general by the reference numeral 10 shown in the open position. Please refer also to FIG. 5 for an illustration of proposed modifications that can be made to the collapsible luggage of FIG. 1.

The luggage 10 includes a planar bottom 12, and four planar upright sides 14, 16, 18, 20 that are perpendicular with respect to the planar bottom 12 when the luggage 10 is in the open position.

A hinged planar top 22 is parallel to the planar bottom 12 and disposed a distance therefrom that is equal to the height of the upright sides 14 20.

The top 22 includes a pair of top hinges 24 that form an axis about which the top 22 can rotate from the open position (shown) into a closed position as indicated by movement along a direction as shown by arrow 26 until it is on top of the upright sides 14 20 and parallel with the planar bottom 12.

There are many ways of securing the luggage 10 in either the open position or in the collapsed position (which is described in greater detail hereinafter). One such way includes the use any well known latch mechanism.

An alternative way includes the use of a hook and loop member 28 disposed on top of the top 22 and a strap 30 that is attached at one end to the planar bottom 12. The strap 30 includes a pair of corresponding opposite hook and loop members 32, 34 that are adapted to adhere with the hook and loop member 28 if pressed together.

The first of the corresponding opposite hook and loop members 32 is used to secure the top 22 in the closed position when the luggage 10 is in the open position. The second of the corresponding opposite hook and loop members 34 is used to secure the top 22 in the closed position when the luggage 10 is in the closed position.

Of course still other ways of closure may be utilized. For example, the strap 30 can be omitted and replaced with a first tie strap 38. Similarly, the hook and loop member 28 can be omitted and replaced with a second tie strap 36. The first and second tie straps 38, 36 are then tied together as desired to secure the top 22 in the closed position whether the luggage 10 is in the open or in the collapsed position.

The planar bottom 12, the upright sides 14 20, and the top 22 are all formed of a rigid material. This is important because it helps the luggage 10 form a substantially rigid structure when in the open position. This provides optimum protection for articles that are placed in the luggage 10.

Each of the upright sides 14 20 is preferably attached to the planar bottom 12 by the use of at least one side hinge 40. More than one side hinge 40 can of course be used. Each side hinge 40 can include a spring 42, if desired, to supply a force that tends to urge each of the upright sides 14 20 downward toward the center of the planar bottom 12 and parallel thereto. This is useful in collapsing the luggage 10.

Each of the upright sides 14 20 includes a flexible corner 44, 46, 48, 50 on each end thereof. Each of the upright sides 14 20 includes an angled end, as illustrated by a first end 16a and a second end 16b.

The angled ends 16a, 16b of all of the upright sides 14 20 are at a forty-five degree angle or less with respect to an edge of the upright sides 14 20 where each side hinge 40 is attached. This allows the upright sides to fold inward (see FIG. 3) without any of the upright sides 14 20 making contact (i.e., being on top of) an adjacent one of the upright sides 14 20. This results in attaining minimum size in the collapsed position (see FIG. 2).

Each of the flexible corners 44 50 is made of fabric or other flexible material. If desired, a zipper 52 can be used to separate the corners to make it easier to fold the luggage 10 into the collapsed position as shown in FIG. 2. If the zipper 52 is used, it is possible to eliminate most of the flexible corners 44 50 except for a small portion where the sides of the zipper 52 attach to the upright sides 14 20. This permits almost the entire length of each of the upright sides 14 20 to be rigid.

A handle 54 is attached to any of the upright sides 14 20 and is used to carry the luggage in either the open or the collapsed positions.

Referring now in particular to FIG. 2, a modified top 22a is shown. The modified top 22a is not attached by the top hinges 24 to the upright side 20. Instead, a second strap 56 that is constructed identical to the strap 30 is used on the other side to secure the modified top 22a in the closed position in either the open or the collapsed positions.

The modified top 22a provides two benefits. The first benefit is that it can be removed entirely from the luggage 10 during loading and unloading. This makes it easier as the modified top 22a cannot possibly be in the way. The second benefit is that the modified top 22a rests flat on top of the luggage 10 in the collapsed position without extending beyond one of the upright sides 16, as would the top 22.

Other ways of attaching a still further modified top are anticipated. For example, the further modified top (not shown) could include a zipper all around that connects with the top edges of four modified upright sides, thereby providing maximum containment of any cargo placed therein.

Referring now to FIG. 4, a second modified top 60 is attached to a modified side panel 62. The side panel 62 is attached to a bottom edge 63 of a modified collapsible luggage 64. The side panel 62 is either solid or flexible, as desired. Please refer also to FIG. 6 for an illustration of proposed modifications that can be made to the collapsible luggage of FIG. 1.

The side panel 62 can remain attached to the bottom edge 63 or it can be modified so that it can be detached from the bottom edge 63 by an edge zipper 66 that folds in toward the second modified top 60. When the second modified top 60 is placed on top of the modified collapsible luggage 64, it does not extend beyond the overall size.

If preferred, an alternate edge zipper 68 could be attached between the side panel 62 and the second modified top 60 providing a similar benefit.

If the side panel 62 is not detachable, then the edge zipper 66 and the alternate edge zipper 68 are eliminated and the flexible side panel 62 is folded underneath the modified top 60 and the rest of the modified collapsible luggage 64 when it is compressed.

There are numerous modifications that are possible. This disclosure can describe but a few of these many possibilities. For example, wheels could be added, as is well known in the luggage arts, to allow for easier transportation when the collapsible luggage 10 (or any modification thereof) is loaded. As another example, any combination of rigid or flexible material can be used. For example, the same flexible material that the flexible corners 44 50 are made of could also be used to form the remainder of the collapsible luggage 10. any of the hinges herein described can be distinct hinges that are added (for example to rigid portions of the luggage 10) or they may be formed of the flexible material that also acts as a hinge.

Another method to secure the second modified top 60 of the modified collapsible luggage 64 (or the top 22 of the collapsible luggage 10) in both the closed position and the collapsed positions is shown in FIG. 4 in which a first half of a perimeter zipper 70 is attached around at least a portion of the second modified top 60. Preferably it extends around three sides 74a, 74b, and 74c, as shown.

A first corresponding second half of a perimeter zipper 76 is attached to the top rim (i.e., the top edges of three of the sides) of the modified collapsible luggage 64. The first corresponding second half of a perimeter zipper 76 mates with the first half of a perimeter zipper 70 to secure the second modified top 60 in a closed position when the modified collapsible luggage 64 is being used to transport items. If the three sides 74a, 74b, and 74c are secured by the zippers 70, 76 and the remaining edge is attached to the side panel 62, then the items in the modified collapsible luggage 64 are retained therein.

A second corresponding second half of a perimeter zipper 78 is attached to a first side of an intermediate section of fabric 80. The intermediate section of fabric 80 includes an opposite side that is attached to the bottom of the modified collapsible luggage 64. The intermediate section of fabric 80 and the second corresponding second half of a perimeter zipper 78 extends around a bottom perimeter of the modified collapsible luggage 64 so as to align generally below the first half of a perimeter zipper 70.

The second corresponding second half of a perimeter zipper 78 is adapted to also mate (i.e., cooperate) with the first corresponding perimeter zipper 76 to secure the modified collapsible luggage 64 in the collapsed position. The intermediate section of fabric 80 allows room for the collapsed portions of the modified collapsible luggage 64 that are compressed between the second modified top 60 and the bottom of the modified collapsible luggage 64.

The invention has been shown, described, and illustrated in substantial detail with reference to the presently preferred embodiment. It will be understood by those skilled in this art that other and further changes and modifications may be made without departing from the spirit and scope of the invention which is defined by the claims appended hereto.
